Python Program to Remove Odd Index Characters in a String

Write a Python program to Remove Odd Index Characters in a String with a practical example.

Python Program to Remove Odd Index Characters in a String Example 1

This python program allows the user to enter a string. First, we used For Loop to iterate each character in a String. Inside the For Loop, we used the If statement to check whether the index value is divisible by true or not. If True, add that character to str2 string. Please refer String article to know about Python Strings

# Python Program to Remove Odd Index Characters in a String
 
str1 = input("Please Enter your Own String : ")

str2 = ''

for i in range(len(str1)):
    if(i % 2 == 0):
        str2 = str2 + str1[i]
        
print("Original String :  ", str1)
print("Final String :     ", str2)

Program to Remove Odd Index Characters in a String Example 2

This program program to remove odd index characters is the same as above. However, we just replaced the For Loop with Python While Loop.

# Python program to Remove Odd Index Characters in a String
 
str1 = input("Please Enter your Own String : ")

str2 = ''
i = 0

while(i < len(str1)):
    if(i % 2 == 0):
        str2 = str2 + str1[i]
    i = i + 1
        
print("Original String :  ", str1)
print("Final String :     ", str2)

Program to Remove String Characters at Odd Index Example 3

The remove odd index Characters in a Python string is the same as the first example. However, this time we used Python Functions to separate the logic.

# Python program to Remove Odd Index Characters in a String
 
def newString(str1):
    str2 = ''

    for i in range(len(str1)):
        if(i % 2 == 0):
            str2 = str2 + str1[i]
    return str2

string = input("Please Enter your Own String : ")       
print("Original String :  ", string)
print("Final String :     ", newString(string))
